Low Temperature STM

This Omicron setup allows performing atomically resolved STM topography and spectroscopy measurements at 5 K and a pressure of less than 10-11 torr. The setup is also able to detect very small numbers of photons generated by the tunnel process. These STM induced luminescence measurements are both spectrally and spatially resolved. The setup also encompasses tip and sample preparation facilities for future spin-polarized STM measurements.
